The Oatey MODA 37611 washing machine outlet box provides recessed water supply connections and a waste drain for washing machines in residential and commercial applications. The box system is constructed from PVC and features two-piece forged brass (C37700) valves with F1807 PEX crimp connections for the supply lines. Stainless steel retention clips secure the valves, which are equipped with Quiet Pipes® water hammer arrestors to mitigate water pressure shock. The dual-box design includes interlocking wing flanges, allowing flexible installation on a single stud, between studs, or on separate walls. It includes a 2-inch drain opening for PVC or ABS Schedule 40 DWV pipes, a removable quarter-turn plug for DWV testing, and an emergency drain port. Valves are rated for 150 PSI air and 250 PSI water pressure. The boxes are IAPMO-Listed, valves comply with ASME A112.18.1 / CSA B125.1 and NSF / ANSI 61 & 372, and hammer arrestors meet ASSE 1010 standards
